Prior Fever in a Returning Traveler – PEARLs Remember that in any returning traveler with a fever we must investigate the TRAVEL hx, EXPOSURE hx and INCUBATION period. Incubation time may be hard to determine, however use less than or more than 3 weeks or 21 days as your cut-off to help narrow your ddx (see chart below) #Diagnosis #Fever #Traveler #Cutoff #Subacute #Acute #Differential
